There were some passion fruits, lemons and mangosteens. The number of passion fruits was two times the number of lemons. The total number of passion fruits and lemons was half of the number of mangosteens. There were 153 fruits altogether. All the mangosteens were sold at 6 for $14. How much money was collected from the sale of the mangosteens?
Number of lemons = 1 u
Number of passion fruits = 2 u

Total number of lemons and passion fruits
= 1 u + 2 u
= 3 u

Number of mangosteens
= 2 x 3 u
= 6 u

Total number of fruits
= 1 u + 2 u + 6 u
= 9 u

9 u = 153

1 u = 153 ÷ 9 = 17

Number of mangosteens sold
= 6 u
= 6 x 17
= 102

Number of sets of 6 mangosteens
= 102 ÷ 6
= 17

Amount collected from the sale of mangosteens
= 17 x 14
= $238

Answer(s): $238
